On a bumpy or rutted roadDrive as slow as possible when driving on bumpy or rutted
roads or over pothole etc.
CAUTION
!Driving on bumpy, rutted roads or over potholes can
damage the tires and wheels.
Wheels with low-profiles tires or under-inflated tires
are especially at risk for damage.The vehicle’s body, bumper, muffler and other parts
may be damaged if the vehicle is:
• driven over a step (for example, at the entrance or
exit of a parking lot);
• parked too closely against a curb or parking block,
or by the side of a road with curbstones;
• driven on a steep slope.

Treadwear, Traction and Temperature GradesTreadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a
specified government test course. For example, a tire graded
150 would wear one and one-half (1
1/2) times as well on the
government course as a tire graded 100. The relative perfor-
mance of tires depends upon the actual conditions of their use,
however, and may depart significantly from the norm due to
variations in driving habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B and
C. Those grades represent the tire’s ability to stop on wet pave-
ment as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Temperature
The temperature grades are A (the highest), B and C, represent-
ing the tire’s resistance to the generation of heat and its ability
to dissipate heat when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained high tempera-
ture can cause the material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to sudden tire fail-
ure. The grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the
minimum required by law.
Tire inflation pressures
N00939300831
Proper tire inflation pressure is essential for the safe and satis-
factory operation of your vehicle. The wrong tire pressure will
cause problems in three major areas:
Safety
Too little pressure increases flexing in the tire and can
cause tire failure. Too much pressure can cause a tire to
lose its ability to cushion shock. Objects on the road and
potholes could then cause tire damage that may result in
tire failure.
Economy
The wrong tire pressure can cause uneven wear patterns in
the tire tread. These abnormal wear patterns will reduce
the tread life, and the tire will have to be replaced sooner.
Too little pressure also makes it harder for the tire to roll,
and this uses up more fuel.
Ride comfort and vehicle stability
The superior riding experience built into your vehicle
partly depends on the correct tire pressure. Too much
pressure gives an uncomfortable and jarring ride. Too lit-
tle pressure feels as if your vehicle is slow to respond.
Unequal tire pressures can make steering your vehicle
uneven and unpredictable.
The correct tire pressure for your vehicle is listed on the plac-
ard attached to the driver’s door sill.
(Refer to “Tire and loading information placard” on page 9-4.)

Tire maintenance
N00939700167
The following maintenance steps are recommended:
Check tire pressures regularly.
Have regular maintenance done on the wheel balance and
front and rear suspension alignment.
Rotate your tires regularly as described in the “Tire rota-
tion” section on page 7-26.
CAUTION
!Avoid using different size tires and wheels from the
ones listed, and avoid the combined use of different
types of tires and wheels. Using different size or type
tires and wheels may affect driving safety.
Refer to “Tires and wheels” on page 9-8.Even if a wheel has the same rim size and offset as
the specified type of wheel, its shape may prevent it
from being fitted correctly. Consult an authorized
Mitsubishi Motors dealer or a repair facility of your
choice before using wheels that you have.As your vehicle is equipped with a tire pressure
monitoring system, use only Mitsubishi genuine
wheels.
Other wheels do not permit correct installation of
tire inflation pressure sensors and can cause air
leakage and sensor failure, which would not be cov-
ered by your vehicle’s warranty.
See an authorized Mitsubishi Motors dealer when
you replace a tire or wheel.

Tread wear indicators
N00939800054
Tread wear indicators are built into the original equipment tires
on your vehicle to help you know when your tires should be
replaced. Many states have laws requiring that you replace
your tires at this point.
These indicators are molded into the bottom of the tread
grooves and will appear when the tire tread is worn down to
1/16 inch (1.6 mm).
When the bands appear next to one another in two or more
places, replace your tires. NOTETire wear indicators can have different marks and loca-
tions depending on the tire manufacturer.
Tire rotation
N00939900390
To even out the wear on your tires and make them last longer,
Mitsubishi Motors Corporation recommends that you rotate
your tires at the mileage listed in the “WARRANTY AND
MAINTENANCE MANUAL”.
However, the timing for tire rotation may vary according to
your vehicle condition, road surface conditions, and your own
personal driving habits. Any time you notice unusual wear,
rotate your tires as soon as possible.
When rotating tires, check for uneven wear, damage, and wheel
alignment. Abnormal wear is usually caused by a wrong tire
pressure, wheels that are not aligned properly, wheels that are
out-of-balance, or severe braking.
Check with an authorized Mitsubishi Motors dealer or a repair
facility of your choice to find out the reason for uneven tread
wear.
The first tire rotation is the most important one. It will allow all
your tires to wear evenly.

CAUTION
!If the tires have arrows (A) indicating the correct
direction of rotation, swap the front and rear tires
on the left-hand side of the vehicle and the front and
rear tires on the right-hand side of the vehicle sepa-
rately. Keep each tire on its original side of the vehi-
cle. When installing the tires, make sure the arrows
point in the direction in which the wheels will turn
when the vehicle moves forward. Any tire whose
arrow points in the wrong direction will not perform
to its full potential.

Snow tires
N00940000362
In some areas of the country, snow tires are required for winter
driving. If snow tires are required in your area, you must
choose snow tires of the same size and type as the original tires
provided with your vehicle. Snow tires should also be installed
on all four wheels. Otherwise your safety and vehicle handling
can be reduced.
Even where laws may permit it, snow tires should not be oper-
ated at sustained speeds over 75 mph (120 km/h).
CAUTION
!Avoid the combined use of different types of tires.
Using different types of tires can affect vehicle per-
formance and safety.
Front
CAUTION
!Change to tapered nuts when using snow tires with
steel wheels. As your vehicle is equipped with a tire pressure
monitoring system, use only Mitsubishi genuine
wheels.
Other wheels do not permit correct installation of
tire inflation pressure sensors and can cause air
leakage and sensor failure, which would not be cov-
ered by your vehicle’s warranty.

During cold weather Salt and other chemicals spread on winter roads in some geo-
graphical areas can have a detrimental effect on the vehicle
underbody. You should flush the underbody with a high pres-
sure hose every time you wash the outside of your vehicle.
Take special care to remove mud or other debris which could
trap and hold salt and moisture.
After washing your vehicle, wipe off all waterdrops from the
rubber parts around the doors to prevent the doors from freez-
ing.NOTEWhen the door is frozen, opening it by force may tear off
or crack the rubber gasket installed around the door. Pour
warm water to melt the ice. Be sure to thoroughly wipe off
the water after opening the door. To prevent freezing of
the weatherstripping on the doors, hood, etc., treat with
silicone lubricant.
CAUTION
!When washing the underside of your vehicle or the
wheels, wear a pair of rubber gloves to protect your
hands.Never spray or splash water on the electrical parts
in the engine compartment. This may damage them.
Be careful also when washing the underbody. Do not
spray water into the engine compartment.Avoid automatic car washers that use rotating
brushes. These brushes may scratch the paint sur-
face and make it dull.
Scratches are more noticeable on darker colored
vehicles.Some hot water washing equipment uses high pres-
sure and heat to clean your vehicle. This heated
water may damage your vehicle’s resin parts. It can
flood the interior of the vehicle. Therefore, be sure
of the following:
• Keep the washing nozzle at least 20 inches (50 cm)
away from the vehicle body.
• When washing around the door glass, hold the
nozzle at a distance of more than 20 inches (50 cm)
and at right angles to the glass surface.
• It is recommended that the water should be
sprayed at a 45° angle to the side windows and top
seals. (ECLIPSE SPYDER only)
Make sure to do the following when using an auto-
matic car wash, with help from either this manual or
the car wash operator, to avoid damaging your vehi-
cle:
• Fold the outside rearview mirrors.
• Remove the antenna.
• Tape or remove the rear wiper arm assembly.
